You guys rock and I'll be a customer for life. Gouging people who care about the sport, that's just shitty business practices. I hope people remember this down the road.
You guys freaking rock for actually putting data behind this, rather than opinions on gun forms. I've shot hundreds of 9mm loaded with small rifle (DA/SA CZ) primers, and I've had no pressure issues.
Been doing it for years, started by working up reduced loads with magnum and rifle primers just to be safe until I reached max loads and found out there were no pressure signs and virtually no difference
@@tn-s197 If you go to forums it's probably the number 1 question asked in primer shortages like this. So many chime in saying you will blow up your gun, it's not safe , you will blow your hand off. It's laughable on sites gun forums how many so called experts no nothing. Shoot safe and have fun.
Just to elaborate on what knowledge I have gathered small pistol magnums are almost exactly a reg small rifle as far as cup thickness and most all small primers do not differ on their charge it all has to do with what pressure they can withstand from the load....small pistol magnums for example are made thicker inside to withstand higher pressures from magnum loads....so while I have had no bad experience using heavier primers in lighter loads I try to not reverse the concept....example being I wouldn't use a standard small pistol primer in a small rifle cartridge that had a lot higher case pressure than most small pistols...if I had to I'd use a magnum pistol primer and be careful working up the load.....but as far as using magnums and rifles in pistol cartridges, basically as long as it will set it off you are good.....
I inadvertently loaded a few hundred rounds with small rifle primers last year and when I realized my mistake I was concerned about firing them. I spoke to a few knowledgeable people and they said said it was ok and not to worry. No one could tell me why though. Now I understand.
I believe Rifle primers are 0.005" longer than Pistol primers... so you may need to seat them a little harder to be flush. At least this is what I found when measuring Large Pistol and Rifle primers. I did not measure the 'small' rifle/pistol primers.
What about this one I’ve seen doing the rounds, just wondering what your thoughts are about these guys that are using cap gun powder & even the old normal strike anywhere match head scrapings to then “reuse” the ammo, case /primer & bullet. I must admit to flinching on his first shots and I wasted even there. I don’t want an argument about this, I just want to start a conversation on this issue, I personally would only use this as a extremely last resort kinda thing but I must admit that they seemed just as good as the normal stuff but would in no way want to have to rely on them. Especially if I had them a week or two. . Thanks 😊
Im 65 been reloading since teenager i knew these facts but nice to see guys telling people reality and facts concerning pressure levels . Thanks for this public service you guys are great

You win the UA-cam video of the year award. I've been staring at several thousand wolf small rifle primers in my reloading room for the last 6 months. I spoke with a customer service rep for one of the powder manufacturers and asked if I could substitute Magnum or rifle primers in my 9 mm loads. I thought he was going to jump through the phone. He said it wasn't safe.I've used small pistol Magnums in my 9-mill loads before without issue. I was reluctant to use the small rifle primers. I strongly recommend anyone doing this and using a Glock pistol install one of the wolf extra power firing pin springs. It is a 6 lb spring compared to the factory 5.5 lb. It does not increase trigger pull much at all. It provided 100% reliable ignition with my Magnum primers. I had about 10% fail to fire when I used the factory spring in a Gen 5 Glock 19. Thanks again for putting out a useful video with actual pressure test data. No one else has done this

One time I screwed up and bought large pistol magnum primers to use to reload .45 ACP. When I shot them, i noticed no difference in performance or accuracy. Your video confirms that there is really not much difference. It's a great video and confirms that it's safe to use the wrong primers and that you won't blow up your gun or injure yourself. Thanks for clearing up any of the myths that exist.
Very cool info. I actually have a considerable amount of small rifle primers, but I no longer have a small rifle. So... this info was invaluable. THANKS!!!
Awesome information. No one I know personally , who reloads , has been able to answer my questions on primers the way you have in 10 minutes. Great content! Thank you!
Wow thank you! I have been reloading for 43 years and always wondered about this primer data. Thank you so much for doing the legwork and testing. Amazing results.
I know I'm very late getting to watch this and comment, but I just wanted to tell you how much I appreciate good information. Not just your say so, but the on camera testing to confirm it. I'm a new reloader, and just about to finish my first box of Remington primers for 9mm. Its a milestonte, from nervous Nellie to tweaking, the quality of my ammo, and having someone( a competition shooter) teach me the safe habits of reloading and how to conduct load developement . Thanks again, its amazing I am always learning.
Beautiful. You’ve answered an age old question for me and all of us, as a lifelong handloader. Thank you! I’ll be sending you some business. I’m one of the lucky ones who stocked up deep and heavy. Tons of primers of all types.
Excellent...I've been reloading since 1974...until now this has never been an issue. Thanks for showing us reloaders this data...Until just recently...before I found 3K S P primers..I considered using S R...but hesitated..
I had heard in the CCI primers that there was virtually no difference between small magnum and small rifle. I had already decided that when things return to normal I was switching exclusively to small rifle for all my needs, this just helped confirm my decision.
This is partially true. CCI small rifle mag and small pistol mag are the same. Their standard small rifle and pistol are also the same. During the Obama great primer shortage I found this out from one of my neighbors in Idaho that works for CCI. I loaded up close to a thousand rounds of .223 with CCI small pistol primers. Not one blown primer out of my rifles.
@@chrisfloyd8512 You’re wrong sir and shouldn’t be giving out false information. Small pistol and small rifle ARE different in terms of cup thickness as stated in this video. Just because you got away with using small pistol primers in your rifle cartridges doesn’t mean everyone will fair so lucky. The other way around is much safer however light strikes are likely using small rifle in a pistol but no chance of damaging yourself our your gun from a blown out primer.
The video that gave me all the answers without wasting ammo, primers and time to test and chrono loads with diff primers. I’ve been reloading for 10+ years but never bothered to look this up. Thank you!!!
Dude I’m so happy I seen this video. I been using small pistol Magnum primers for my reloading of 223. 52 grain . And I have to say they work great . But was looking for a answer And you answered it thank you 🇺🇸
Based on the info, I will go the other way around. Have small rifle, bur can't find SPM locally - or at gun shows, either.Now will load my .357 mag s with small rifle.

Smiling! Thank You! I just loaded a couple hundred 9mm with small rifle primers CCI 400 (out of CCI 500) tested them yesterday with 3 of my 9mm and they all did well with them. I checked the specs and the one thing I did run into was the primer is just a little longer and you have to press harder are you get a little wobble when you set them butt down on the desk, I needed the right arm work out anyway.

Thank you for performing this benchmark. It cleared some things up. ‘This primer shortage is frustrating. Like everyone else I listened to the CEO of Federal explain that they are using 100% of their primer capacity to manufacture their own ammo so there is nothing left for the smaller ammo manufacturers or reloaders. Yet when I go to Canada all their gun stores and Many retail stores like Walmart have no ammo shortage and all kinds of U.S. primers on the shelf and available to Canadian reloaders. Why are the U.S. manufacturers shipping their primers to Canada and not using them to make their ammo?
I tried to tell several of my friends. If they have a lot in Canada. And almost none here. It's because of our curupt Socialist government. It's the same with powder and bullets. If anyone says different I would not believe them.
The BATF&E changed the rating on powder. They raised the hazard rating on the powder. That means that they put more of a limit on the amount of powder per container.
OUTSTANDING video! So, the different primers are only about cup thickness and nothing more. I have been reloading 30 years and did not know that; I was merely listening to the conventional wisdom. This is great news, also, because I have a few SPPs and SPMPs but I have lots of SRPs which I can use to reload in pistols. Awesome. DATA, baby!
Thanks so much for this great informative video on an important safety factor of primer use and applications. Recently I used some old CCI Small Rifle Primers in 45 APC equipped with the SP primer pockets. Chronograph showed appx. 2-3.5 FPS faster speeds, but no pressure signs at all, using IMR 700X powder. I use a Frankford Arsenal hand held primer installation tool, equipped with adjustable primer depth setting. I set all of my primers @ .002"-.003" below the surface or past flush. When I measured the primers, both the SR and SP are exactly the same dimensions in depth and diameter, where the LR are different that the LP. Again; thanks to your video with specifications and excellent testing, I am comfortable to have checked my use of the SR primer in my 45s.
Great video and tons of respect to you for putting it out there. Reasonable prices too. You've got yourself a new customer. When stuff is back in stock you'll be my go to. Thanks

Thank you. I’ve been looking for this kind of information. Why this doesn’t show up higher in search results baffles me. Just wish I’d been able to find this video sooner.
Really appreciate you tackling this topic. I picked up 6k Federal Small Pistol Magnum primers for around $25/1000 a year ago and was trying to trade for regular small pistol but looks like I’ll do load development for them too.
@@danielgato3916 sorry bud, not only do you need a hazmat cert to ship them but I would have to charge you 6 times what I paid because replacement cost is substantially more
Thank you very much for publishing this video. I load different calibers, both pistol and rifle, using their respective “appropriate” primers. Now, I know I can mix and match within certain safety parameters. Much respect, sir! I salute!
This is the best video I've seen all day, thank you so much for sharing this. I have passed by small rifle primers several times thinking them unsuitable for 9mm. Oh well, I won't make that mistake again! On a side note, I learned that it is not wise to (mistakenly) use large pistol primers in place of large rifle primers. Remington packaging looks similar for both, D'Oh! I caught myself after 20 rounds, thankfully. I took a chance and fired them (7x57 Mauser loads, loaded below maximum in the Speer manual). Most were okay, but a couple had minor piercing. I was lucky as well as stupid. After rooting around on the internet I found others that had worse luck than I did with pierced primers on different calibers. The takeaway lesson is to carefully double check ALL of your components and charge weights before proceeding. A kinetic bullet puller is also a sound investment. Great video, thank you!
Great piece. I have been loading for over 50 years and I can tell you he is spot on. I had to load 9mm luger and low and behold I was out of CCI-500 so I substituted CCI-550, 124 gr Nosler, and Hodgen HS-7 (Speer data). No Problem.
Excellent information! The only problem I have had is Sellier & Bellot small rifle in .380 pistol loads. Neither the Kahr CW or Glock 42 would fire the S & B SR (light strikes). I had to pull 100 rds 😬. Should always test a small batch. 👍
Awesome video! Ha ha I just did chrono testing with CCI, Federal, and Winchester small pistol, small pistol magnum, small rifle in 9mm because I was tired of hearing all the “your gun will blow up if you even THINK about using a magnum primer in a non-magnum load!” old wives tales. I found that not only was there no difference in the types of primers, there was essentially no difference across the brands.
Thank you very much for this video! I had heard about people loading 9mm with small rifle primers, and tried it with 7 test rounds in my Glock G45; all 7 rounds shot flawlessly! That said, I was hesitant to make too much of a habit of it, despite me having a good amount of small rifle primers on hand. This video definitely makes me feel more comfortable with doing it!
Outstanding video!!! These are the types of videos that add to all of our knowledge. Truly appreciated. It would be very informative to have a similar video showing the same test with standard large pistol and large pistol magnum primers.
In the old days ( 40 years ago) small primers used to say on the packages small rifle/pistol on them. The large ones are a bit different in height and strength but not pressure. I've only found issues with striker fired weapons sometimes takes two strikes to set off large rifle primers as they are a bit harder. But hammer fired weapons large rifle works great. Magnums just burn hotter but not more pressure. Ivr swapped em all around for the 4+ decades Ive loaded I also reload them. Once used they will work in anything as even the harder large rifle bow have been weakened enough
Thanks so much for cutting to the chase with true scientific data. The numbers don't lie. A chronograph is something most have access to but your Test Barrel and pressure data is the definitive analysis that we are all seeking. You rock! Just bought a Brick of Federal 200 Small Magnum Pistol Primers to feed my 9mm pistol, carbine, and .38 Special EDC. Yes, Sportsmans had five bricks under the counter today. I got lucky. 44 guys at the front door at the opening.
Good to finally see 'hard data' on the opinions of some on shooter forums. Material thickness of the primer body is the only difference, to deal with pressure loads like from .357 magnum & hot loaded .223, etc.
great work.. I think this pretty much concludes that primers don't have an impact on the case pressure, at least in pistol. As long as the primer properly burns all the powder in the case, the pressure or muzzle velocity should be consistent throughout different types of primers.
I didn't get into reloading until the very beginning of woohan. CCI 550 was all I could find, so that is what I worked my load up with from the start. For a while, I was in good shape on the CCI 550s because no one was buying them up, no longer the case. VVN320 and CCI 550s is my preferred combo now, 4.2gr for 124 bullets and 4.8gr for 115s
Awesome. Never had actual proof positive for the primers as shown- so never tried it... now can see its a doable thing. Thank you. By the way - Super Vel is is nice to see- again!
Been curious and a little concerned about this as a new reloader! Just bought some magnum small pistol the other day to try it. Now I feel confident that it's safe and will not hesitate to buy more when I see them. Thanks for the great video!
Thank you Super Vel !! This video is exactly what all reloaders have been wanting to know. I will definitely keep this in mind when buying ammo. I didn't even know people could send primers to Super Vel to have ammo loaded. That is spectacular! Thanks again for info that is actually backed up by real data!!!
I am so glad I stumbled onto this. I never thought to look into the differences and just went by the recipes in the loading books. Thank you for sharing your knowledge.
Thank you for the test video it helped me tremendously because I started loading the 5.7 by 28 now I know the difference between the primers I can use my small rifle primers
I had been looking this info for a year. I had a thousand small pistol magnum primers, but was unsure whether to use them on my 40mm reloads. great video thanks.

Brooooo! This is fucking awesome! Now I have this video to reference when people wanna argue or look at me like I’m completely insane when I suggest that they can substitute primers! I’m almost sad now, bc I have a good bit of small rifle and I just started loading 9mm and I don’t want to use all my primers before they start coming back in stock lol
That's funny. As a machinist with a few decades of experience, I was thinking before watching that probably the only real difference was the thickness of the cup material, and the anneal of the cup to determine how "stiff" it was. Glad to see I was right.
Thank you for your testing. From experience, the S&W M&P and the SCCY 9mm pistols have a hard time firing the small rifle due to the light strikes. Most others seem to fire it well. .380's loaded with 50-60 year old CCI SPM's from a Ruger LCP also functioned well.
CCI #400....it does it all. Loaded probably 100,000 in 9mm. Tested in everything from Gucci Glocks to full-auto MP-5. Shot a ton of rounds to the point I felt that they were reliable enough to sell. It made velocity more consistent. Also works great in 357mag when using magnum powder

CCI small rifle mag and small pistol mag are the same.
Their standard small rifle and pistol are also the same.
During the Obama great primer shortage I found this out from one of my neighbors in Idaho that works for CCI.
I loaded up close to a thousand rounds of .223 with CCI small pistol primers.
Not one blown primer out of my rifles.
@@chrisfloyd8512 You’re wrong sir and shouldn’t be giving out false information. Small pistol and small rifle ARE different in terms of cup thickness as stated in this video. Just because you got away with using small pistol primers in your rifle cartridges doesn’t mean everyone will fair so lucky. The other way around is much safer however light strikes are likely using small rifle in a pistol but no chance of damaging yourself our your gun from a blown out primer.
@@mikerobinson8734 sure thing pal.
The video that gave me all the answers without wasting ammo, primers and time to test and chrono loads with diff primers. I’ve been reloading for 10+ years but never bothered to look this up. Thank you!!!
Dude I’m so happy I seen this video. I been using small pistol Magnum primers for my reloading of 223. 52 grain . And I have to say they work great . But was looking for a answer
And you answered it thank you 🇺🇸
Glad it was helpful for you!
Based on the info, I will go the other way around. Have small rifle, bur can't find SPM locally - or at gun shows, either.Now will load my .357 mag s with small rifle.

Thank you very much.Relieves some of the concern that I had with my Dad’s leftover primers.
No problem! Glad the video helped out
Thanks for the no BS info.
Smiling!
Thank You! I just loaded a couple hundred 9mm with small rifle primers CCI 400 (out of CCI 500) tested them yesterday with 3 of my 9mm and they all did well with them. I checked the specs and the one thing I did run into was the primer is just a little longer and you have to press harder are you get a little wobble when you set them butt down on the desk, I needed the right arm work out anyway. Smiling Big....

Thank you for performing this benchmark. It cleared some things up. ‘This primer shortage is frustrating. Like everyone else I listened to the CEO of Federal explain that they are using 100% of their primer capacity to manufacture their own ammo so there is nothing left for the smaller ammo manufacturers or reloaders. Yet when I go to Canada all their gun stores and Many retail stores like Walmart have no ammo shortage and all kinds of U.S. primers on the shelf and available to Canadian reloaders. Why are the U.S. manufacturers shipping their primers to Canada and not using them to make their ammo?
I tried to tell several of my friends. If they have a lot in Canada. And almost none here. It's because of our curupt Socialist government. It's the same with powder and bullets. If anyone says different I would not believe them.
The BATF&E changed the rating on powder. They raised the hazard rating on the powder. That means that they put more of a limit on the amount of powder per container.
OUTSTANDING video! So, the different primers are only about cup thickness and nothing more. I have been reloading 30 years and did not know that; I was merely listening to the conventional wisdom. This is great news, also, because I have a few SPPs and SPMPs but I have lots of SRPs which I can use to reload in pistols. Awesome. DATA, baby!
Except large pistol and large rifle. Those are different dimensions
Thanks so much for this great informative video on an important safety factor of primer use and applications. Recently I used some old CCI Small Rifle Primers in 45 APC equipped with the SP primer pockets. Chronograph showed appx. 2-3.5 FPS faster speeds, but no pressure signs at all, using IMR 700X powder. I use a Frankford Arsenal hand held primer installation tool, equipped with adjustable primer depth setting. I set all of my primers @ .002"-.003" below the surface or past flush. When I measured the primers, both the SR and SP are exactly the same dimensions in depth and diameter, where the LR are different that the LP. Again; thanks to your video with specifications and excellent testing, I am comfortable to have checked my use of the SR primer in my 45s.
This is the best video on being able to mix primers thanks for the info
Very well spoken. Appreciate you taking the time to make this video. Thanks again, Travis; 2A Tactical LLC Boise, ID
Great video and tons of respect to you for putting it out there. Reasonable prices too. You've got yourself a new customer. When stuff is back in stock you'll be my go to. Thanks
Happy the video was of value to you, and glad to hear we have a new customer. We really appreciate all of the support!

Thanks for the heads up. I really appreciate the information on small rifle primers being used in small pistol cartridges.
Thank you. I’ve been looking for this kind of information. Why this doesn’t show up higher in search results baffles me. Just wish I’d been able to find this video sooner.
Thank you I was down to 3000 small pistol primers. But have almost 10,000 small rifle primers.
No problem! Glad to hear it!
Same here. Now I can put a few thousand small rifle primers to work
Now If I had 12,000 bullets and more powder
Everglades for bullets. Powder youre on youre own
Really appreciate you tackling this topic. I picked up 6k Federal Small Pistol Magnum primers for around $25/1000 a year ago and was trying to trade for regular small pistol but looks like I’ll do load development for them too.
Glad we could help!
Hey!! Just saw your comment and was wondering if you we willing to sell any of your primers! Please let me know
@@danielgato3916 sorry bud, not only do you need a hazmat cert to ship them but I would have to charge you 6 times what I paid because replacement cost is substantially more
Thank you very much for publishing this video. I load different calibers, both pistol and rifle, using their respective “appropriate” primers. Now, I know I can mix and match within certain safety parameters. Much respect, sir! I salute!
Our pleasure! Thanks for watching
Reloading manuals that I have read say don't mix. You are the first source that I have heard say it is ok. In a pinch I would do it.
You guys are awesome, one of the few companies that prioritize the customer. Customer for life right here!
Thank you for your kind words and support! It means a lot to us!
Awesome information. Thank you.
This is the best video I've seen all day, thank you so much for sharing this. I have passed by small rifle primers several times thinking them unsuitable for 9mm. Oh well, I won't make that mistake again! On a side note, I learned that it is not wise to (mistakenly) use large pistol primers in place of large rifle primers. Remington packaging looks similar for both, D'Oh! I caught myself after 20 rounds, thankfully. I took a chance and fired them (7x57 Mauser loads, loaded below maximum in the Speer manual). Most were okay, but a couple had minor piercing. I was lucky as well as stupid. After rooting around on the internet I found others that had worse luck than I did with pierced primers on different calibers. The takeaway lesson is to carefully double check ALL of your components and charge weights before proceeding. A kinetic bullet puller is also a sound investment. Great video, thank you!
A really outstanding video. No opinion, no theory, just facts.
Thanks, glad you liked it!
Been doing this for years. But it never fails some safety Karan comes along and tells me I’m unsafe. So I leave it to myself. Thanks
You've been ahead of the game it appears!
Great piece. I have been loading for over 50 years and I can tell you he is spot on. I had to load 9mm luger and low and behold I was out of CCI-500 so I substituted CCI-550, 124 gr Nosler, and Hodgen HS-7 (Speer data). No Problem.
My shelf is loaded with all 3
You made me very happy
Thank you
No problem!
Good info. I’m loading 9mm with small pistol magnum primers and now you have given me the data that I needed. Thanks
Great ammo, Great service, no gouging, keeps us up to date on ammo, thank you for being an honest American company
Excellent information! The only problem I have had is Sellier & Bellot small rifle in .380 pistol loads. Neither the Kahr CW or Glock 42 would fire the S & B SR (light strikes). I had to pull 100 rds 😬. Should always test a small batch. 👍
Thanks for that info!
thank you for dispelling myths and putting facts out there for all of us shooting during Primergeddon .
Thanks big time for the video we already knew small P and small R interchange, but weren't sure to try put small R primers in 9mm cases. AWESOME !!!
Awesome video! Ha ha I just did chrono testing with CCI, Federal, and Winchester small pistol, small pistol magnum, small rifle in 9mm because I was tired of hearing all the “your gun will blow up if you even THINK about using a magnum primer in a non-magnum load!” old wives tales. I found that not only was there no difference in the types of primers, there was essentially no difference across the brands.
Glad you enjoyed the video!
Excellent video, a friend asked me about using small rifle primers for pistol loads. Now I can reassure him it is fine. Thank you so much!
Great ammo, good prices, no gouging, let's keep a great American company going that is doing their best for us
Thank you very much for this video! I had heard about people loading 9mm with small rifle primers, and tried it with 7 test rounds in my Glock G45; all 7 rounds shot flawlessly! That said, I was hesitant to make too much of a habit of it, despite me having a good amount of small rifle primers on hand. This video definitely makes me feel more comfortable with doing it!
Glad to hear the video was beneficial!
Thanks for clearing this issue. Ill be getting you my primers soon. Sucks my local ups won't ship them, but I'll figure it out. Thanks.
Sounds good!
Don’t tell them what they are
@@wannabe4668 Have to, Super Vel will not except the package without the hazmat notice.
Awesome information. I have so many small rifle primers and really was not sure if I could load them in place of my small pistol so this helps a bunch
Excellent publication, timely and very helpful.
Glad you liked it!
Outstanding video!!! These are the types of videos that add to all of our knowledge. Truly appreciated. It would be very informative to have a similar video showing the same test with standard large pistol and large pistol magnum primers.
Thank you for the kind words and for watching! We have more videos in the works!
Excellent video. Thanks for taking the time to run the tests and present the facts.
Our pleasure! Glad it was beneficial for everyone!
In the old days ( 40 years ago) small primers used to say on the packages small rifle/pistol on them.
The large ones are a bit different in height and strength but not pressure.
I've only found issues with striker fired weapons sometimes takes two strikes to set off large rifle primers as they are a bit harder. But hammer fired weapons large rifle works great.
Magnums just burn hotter but not more pressure.
Ivr swapped em all around for the 4+ decades Ive loaded
I also reload them. Once used they will work in anything as even the harder large rifle bow have been weakened enough
Thanks so much for cutting to the chase with true scientific data. The numbers don't lie. A chronograph is something most have access to but your Test Barrel and pressure data is the definitive analysis that we are all seeking. You rock! Just bought a Brick of Federal 200 Small Magnum Pistol Primers to feed my 9mm pistol, carbine, and .38 Special EDC. Yes, Sportsmans had five bricks under the counter today. I got lucky. 44 guys at the front door at the opening.
Good to finally see 'hard data' on the opinions of some on shooter forums. Material thickness of the primer body is the only difference, to deal with pressure loads like from .357 magnum & hot loaded .223, etc.
1 lab test is worth 1000 expert opinions!
great work.. I think this pretty much concludes that primers don't have an impact on the case pressure, at least in pistol. As long as the primer properly burns all the powder in the case, the pressure or muzzle velocity should be consistent throughout different types of primers.
I ordered several of your SCHP 9mm and glad to have them, though I'll probably never fire them! Just one of those "Piece Of Mind" to have.
We appreciate your business and support!
@@SuperVelAmmo looking forward to getting some TRAINING and COMPETITION ammo from you!!!!
Fantastic video. I've been using small mag primers in my 38spl loads for years.
Glad you liked it! Thanks for watching!
I didn't get into reloading until the very beginning of woohan. CCI 550 was all I could find, so that is what I worked my load up with from the start. For a while, I was in good shape on the CCI 550s because no one was buying them up, no longer the case. VVN320 and CCI 550s is my preferred combo now, 4.2gr for 124 bullets and 4.8gr for 115s
Yeah once the primer run started, it's been tough to get anything!
Thanks for a useful video. I have always wondered what the difference would be. Good to see the Super Vel name still out there.
No problem, thanks for watching! And we're glad to be back!
Awesome. Never had actual proof positive for the primers as shown- so never tried it... now can see its a doable thing. Thank you. By the way - Super Vel is is nice to see- again!
Been curious and a little concerned about this as a new reloader! Just bought some magnum small pistol the other day to try it. Now I feel confident that it's safe and will not hesitate to buy more when I see them. Thanks for the great video!
no problem! Glad it was useful
I have always used Winchester small pistol Magnum with great luck in my 9mm. Great to know that you can use small rifle.
This kind of video makes UA-cam worthwhile. Thank you!
Great video and information! I have some Super Vel 44mags from the 60’s given me by my father👍
Thank you Super Vel !!
This video is exactly what all reloaders have been wanting to know. I will definitely keep this in mind when buying ammo. I didn't even know people could send primers to Super Vel to have ammo loaded. That is spectacular! Thanks again for info that is actually backed up by real data!!!
No problem, thank you for watching!
I am so glad I stumbled onto this. I never thought to look into the differences and just went by the recipes in the loading books. Thank you for sharing your knowledge.
Thank you, I was considering using rifle primers in my 9mm. just like the 38 super guys. But I didn't know who to ask for advise. I will sub.
Brilliant! I have been wondering about this. Now I can start reloading 9mm again.
Awesome video! Thanks for making it! I get into this debate with my customers all the time. Mahalo from Hawaii!
Glad you liked it! Have a good one
Thank you for the test video it helped me tremendously because I started loading the 5.7 by 28 now I know the difference between the primers I can use my small rifle primers
Glad you found it helpful!
I had been looking this info for a year. I had a thousand small pistol magnum primers, but was unsure whether to use them on my 40mm reloads. great video thanks.
Glad it helped you out!

Thanks been using small rifle in my 9mm with zero issues.
As a new to reloading this is very helpful info thanks for shearing.
Brooooo! This is fucking awesome! Now I have this video to reference when people wanna argue or look at me like I’m completely insane when I suggest that they can substitute primers! I’m almost sad now, bc I have a good bit of small rifle and I just started loading 9mm and I don’t want to use all my primers before they start coming back in stock lol
Yes the are. Source, Loaded tons of them. My wife's carry ammo is currently using SR primers.
That's funny. As a machinist with a few decades of experience, I was thinking before watching that probably the only real difference was the thickness of the cup material, and the anneal of the cup to determine how "stiff" it was.
Glad to see I was right.
Thank you for your testing. From experience, the S&W M&P and the SCCY 9mm pistols have a hard time firing the small rifle due to the light strikes. Most others seem to fire it well. .380's loaded with 50-60 year old CCI SPM's from a Ruger LCP also functioned well.
This was great information, truly appreciate you taking the time for this testing!
Likely the most useful video on youtube...cannot thank you enough!
Thanjs for great information.As a new reloader I was curious about this.
Glad to hear it was helpful!
You have gained a future customer. Great video.
That's great to hear! We're glad you enjoyed the video!
CCI #400....it does it all. Loaded probably 100,000 in 9mm. Tested in everything from Gucci Glocks to full-auto MP-5. Shot a ton of rounds to the point I felt that they were reliable enough to sell. It made velocity more consistent. Also works great in 357mag when using magnum powder
Hey Guys, Thank You! I really appreciate this.
no problem, thank you for watching!
Thank you for the testing and results from the testing!
